RAMPS 1.4 Over temp error

I am setting up RAMPS 1.4 for the first time. I have flashed with Marlin. Set board to 33. Have the Thermistors, endstops and Steppers connected. I can connect in Repetier but keep throughing an over temp error when i try to manual jogg like the thermistor is shorted. Changed thermistors, no fix. What have i missed or set up wrong?

Just below the MOTHERBOARD variable in the config file, there are TEMP_SENSOR_# variables which you need to either set to 0 (unused) or choose the proper value from the list.

This?
#define TEMP_SENSOR_0 -1
#define TEMP_SENSOR_1 -0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 0

4

To this?

#define TEMP_SENSOR_0 -51
#define TEMP_SENSOR_1 -0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 0

I could be wrong as it’s been a while, change -51 to 51 and -0 to 0

What thermistor are you using?

And did it come with your e3d hotend?

Ya its the E3D thermistor. UPDATE: After trying several different versions of firmware I have found one that it working. There must be some settings in the first ones that i have missed to set correctly.
